We are customers of Keith Key and have been since 2007. We have always received excellent service from this company and their prices are very fair. They installed a new unit for us this past summer and we had some problems with the initial installation of the new unit. Keith Key and his technicians found the issues and corrected them with utmost proficiency. I would highly recommend their services of heating and air in Tallahassee, whether it be a new installation, repairs, or annual checks, as all of my dealings with this company have been above reproach. You will never find a company that is more honest and truly has its customers at heart.
